DRAWING MECHANISM FOR TuBULAR-DESPATCH SYSTEMS?.

SPECIFICATION forming part of Lettere Patent No. 661,363, dated November' 6 190e.

Application led July l0, 1900. Serial No. 23,090. (No model.)

To all whom it may concern.-

.Be it known that I, WASHINGTON A. H. Bo- GARDUS, a citizen of the United States, residing at The Montana, One Hundred and Twenty-fourth street and Mount Morris avenue, in the city of New York,county of New York, and State of New York, have invented a new and useful Improvement in Draining Mechanism for Tubular-Despatch Systems, of which the following is a specification.

My invention relates to improvements in the general class of tubular-despatch systems, and has for its object to carry off moisture and dirt in the form of water caused by condensation and sediment from the tubes of such system.

This object I attain in the manner and by the device shown and described, reference being had to the accompanying drawings, in which- Figure l is a longitudinal vertical section of a transit-pipe with my device applied thereto, and Fig. 2 a cross-section of the same on line X X of Fig. l. e

Like numerals of reference designate similar parts in both views. A

Referring to the drawings, l represents a section of transit-tube; 2, a recess opening from the bottom of tube; 3, a partition in said recess, its upper edge 4 conforming to the inner circumference of the tube l; 5, a drip-pipe located at the point of lowest depression of said recess; 6, a small opening in the bottommost portion of partition 3; 7, a hand-hole for removing obstructions from tube 1; 8, a similar hole for recess 2; 9, ports leading from tube l into recess 2, and l() bridges for strengthening the casting between ports ll.

The operation is as follows: Water and sediment collected in front of a moving carrier would not fall immediately into a short recess as usually provided in the bottom of a tube, as the rapidity of movement of a carrier would convey it beyond such a point. lt is therefore desirable to provide an extended opening for this purpose. A recess of appreciable length is necessary to produce the desired results; but it has been found that the required length of such recess is greater than the length of the generally-used carrier and would therefore allow the air under pressure behind the carrier to pass around it through said recess and the carrier to stop. I therefore provide one or more partitions 3, the distance between the same or between such partitions and the end of ports ll being less than the length of the carrier used, thus preventing the air from so passing around the carrier. I provide a small aperture or apertures 6 at the bottommost point of the partitions 3, the area of which is such as to allow of the passage of water and sediment, but not sufficient to allow of the detrimental leakage of air around the carrier. The fioor of the recess 2 is inclined to a point where such water and sediment is drawn oif from time to time from a pipe 5, provided witha faucet orvalve. I [ind it expedient to allow a little clearage between the upper end of partition 3 and the inside periphery of the transit-pipe at the ports 9 (designated as ll) to prevent the accumulation -of dirt and other obstruction between the partition and packing-rings of the carrier and the consequent jamming thereof. The handholes 7 and 8 are closed with detachable airtight doors.

It is obvious that various changes may be made in the details and construction of this device without departing from the spirit of my invention.

I-Iaving now described my invention, what I claim, and desire to secure by Letters Patent, is-

l. In a drip-receptacle for transit-tube systems, in combination with a transit-tube, a drip-chamber having a plurality of compartments, substantially as and for the purpose set forth.

2. In a drip-receptacle for transit-tube systems, in combination with a transit-tube, a drip-chamber having a plurality of communicating compartments and longitudinal openings from said transit-tube to said compartments, substantially as described.

3. In a dri p-receptacle for transit-tube systems, in combination with a transit-tube, a drip-chamber having a plurality of compartments, means of communication between said compartments, longitudinal openings from said transit-tube to said compartments, and

IOO

a drain-pipe and cock therefor common to all of said compartments, substantially as described.

4. In a drip-receptacle for transit-tube systems, in combination with a transit-tube, a drip-chamber having a plurality of compartments, longitudinal openings from said transit-tube to said compartments, the bottoms or floors of said compartments inclined to a common drain-pipe, means of comm unication between said compartments adjacent said bottoms or floors, a cock for said drainpipe and means of access to said drip-chamber and said transit-tube adjacent said chamber, substantially as described.
